first severing the major woody root mass before extracting the trees, or grinding the stump below ground. Tree Protection During Construction 1. Prior to beginning work, the contractors working in the vicinity of trees to be preserved are required to meet with the Consulting Arborist at the site to review all work procedures, access routes, storage areas and tree protection measures. 2. Any grading,construction,demolition or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist. 3. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied. 4. Fences shall be erected to protect trees to be preserved. Fences are to remain until all site work has been completed. Fences may not be relocated or removed without permission of the project superintendent. 5. Construction trailers,traffic and storage areas must remain outside fenced areas at all times. 6. No materials, equipment, spoil, waste or wash-out water may be deposited, stored, or parked within the Tree Protection Zone(fenced areas). 7. Any additional tree pruning needed for clearance during construction must be performed by a qualified arborist and not by construction personnel. 8. All trees shall be irrigated on a schedule to be determined by the Consulting Arborist. Each irrigation shall wet the soil within the Tree Protection Zone to a depth of 30 inches. 9. Any roots damaged during grading or construction shall be exposed to sound tissue and cut cleanly with a saw. Significant Impact Impact 4.3-2: The project would result in the loss of habitat for the California tiger salamander and individual California tiger salamanders may be taken during construction of the project. Finding Changes or alterations have been required in, or incorporated into,the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential impacts to California tiger salamander to a less-than-significant level: Mitigation Measure 4.3-2a: To mitigate for the loss of aestivation habitat and potential impacts to any aestivating California Tiger Salamander(CTS)on-site,the project applicant shall permanently preserve and manage potential CTS upland aestivation habitat located on the project site between the proposed development area and Pond 2, located on the adjacent Oak Grove property. The amount of such preserved and managed habitat shall be not less than the amount of land developed as a result of project construction (i.e., 1:1 acreage ratio). The applicant shall preserve such habitat through the recording of a deed restriction,conservation easement, or other equivalent instrument which precludes future development or the construction of physical barriers to the movement of CTS across the preserved habitat. The applicant shall also develop, and arrange for the implementation of a habitat management plan for the preserved habitat. Prior to the issuance of a grading permit,the applicant shall provide a copy of the recorded instrument(which will identify the precise size and location of the permanently preserved habitat),the habitat management plan and the federal and state take authorizations to the City. The applicant shall also provide copies of the incidental take authorizations secured for the project from the USFWS and CDFW to the City. LUND RANCH II(PUD-25)RESIDENTIAL PROJECT 6 FINDINGS
